The Urban Dictionary Mug

n. A system of delusions that supports a person's overinflated sense of self-worth and importance. Egosystems are bizarrely robust despite often being overextended and lacking the actual elements that would otherwise legitimize it's sustained existence. Woe to the realist that points out the delusions underpinning an egosystem and potentially (but not likely if you're dealing with a realdouchebag that won't believe you anyway) precipitating egosystem collapse... for shame!

Kanye West's behaviour isn't symptomatic of off-the-charts arrogance, but rather it's a manifestations of his extensive egosystem which simply consumes everything in it's immediate environment.
